The Seattle Mariners are actively seeking to enhance their roster as 2025 approaches, despite not making any trades during the Winter Meetings. Rumors surrounding veteran pitcher Luis Castillo's potential trade have gained traction, particularly in discussions with the Boston Red Sox.

Reports indicate that the Mariners have contacted Castillo's agent regarding the possibility of waiving his no-trade clause. Meanwhile, the Chicago Cubs are exploring options that could influence Seattle's trade strategies, particularly concerning starting pitcher Jesus Luzardo, who offers a more affordable alternative.
